T 0 all whom it may concern:

Be it known that I, FRANK W. EDWARDS, a citizen of the United States,residing at Logansport, in the county of Cass and State of Indiana, haveinvented a certain new and useful Improvement in Sight-Feed Lubricators,of which the following is a full, clear, and exact description.

This invention relates to the class of sight feed condensationdisplacement lubricators wherein, instead of tubular glasses and avertical oil bowl, are used solid panes or pieces of glass and ahorizontal oil bowl.

The object of the invention is to simplify the construction of partssoas to provide for the more perfect control of the fluids passing throughthe lubricator; to admit of the interchange of parts, and the readyapplication or combination of additional feed chambers.

In the accompanying drawings illustratin the several figures of whichlike parts are similarly designated, Figure 1 is an end elevation, withan auxiliary hand feed cup attached and shown in vertical section. Fig.2 is a front elevation. Fig. 3 is a central vertical longitudinal section. Fig. 4 is a top plan view and partial section of the oil bowl.Fig. 5 is a front elevation and partial section of the oil bowl and itsattached sight feeds. Fig. 6 is a vertical section of the top of the oilbowl through the fillinghole. Fig. 7 is a vertical section} takensubstantially in the plane of line AB, Fig. 5. Fig. 8 is an elevationand partial longitudinal section of the condenser and water valvearrangement therein. Fig. 9 is a front elevation of the interchangeablecondenser, showing the application of additional sight feeds to it, theleft-hand sightfeed being shown in longitudinal section, the steam unionbeing omitted. Fig. 10 is a top plan view of the arrangement shown inFig. 9, with the union of Figs. 11 and 12 in place. Fig. 11. is a rearelevation and Fig. 12 is a side or end elevation of a union used inconnection with the modification shown in Figs. 9 and 10.

The oil bowl 1, is, generally speaking, a cylinder arranged with itslongitudinal axis horizontal. This cylinder is made with an and acondenser receiving nipple 3 upon which last the condenser 4 is screwed.The oil bowl may be cast integral with the cylinders 5 at each end and asimilar cylinder 6 at the bottom, and each of these cylinders 5 and 6constitutes, as will presently appear, a feed-chamber in the respectivesight feeds. Each of the end cylinders 5 has a depending tube 7 withwhich communicates a duct 8 preferably made integral with the oil bowl,and opening in the upper end of this oil bowl so as to receive by displacement oil from the said bowl and conduct it down into the tube 7,whence it is displaced through any approved form of nipple or tip 9 intothe feed-chamber of the cylinder 5 from which it rises through the tube10 into the pipe 11, whence it is fed to the part to be lubricated. Thenipple 9 is controlled by a hand-valve 12. At the intersection of thetube 10 and pipe 11 is arranged a valve 13 by which the pipe 11 may beclosed and the feed-chamber and its appurtenances cut off from steamcoming in through pipe 11, so that in case of breakage or damage to thesight feed including the feed-chamber, it may be cut off from the steamand repaired very readily. Each cylinder 5 is provided with a drainagepassage 14 which is controlled by a valve 15.

The cylinder 6 has a depending tube 16 supplied with a nipple or tip 17and a controlling valve 18, and the tube 16 is in communication with theoil bowl by means of a channel 19 and a tube 20 rising to near the topof the oil bowl to receive the displaced oil. The upper portion of thecylinder 6, as shown more particularly in Fig. 3, communicates with achannel 21 which opens into a distributing channel 22; and theintersection of channels 21 and 22 is supplied with a cut-off valve 23by means of which the cylinder 6 may be deprived of steam in case ofbreakage of its glasses. The cylinder 6 is provided with a drainagevalve similar to the drainage valves applied to the cylinders 5, and asshown in detail in Fig. 5. In each of these cylinders 5 and 6 are placedsolid panes or disks or pieces of glass 24;, suitably secured therein byany suitable screw plugs, not shown, screwed into the ends of thecylinders.

The channel 22 crosses the top of the oil bowl, and as shown in Fig. 4,is deflected so as not to interfere with the water-pipe 25 dependinginto the oil bowl from the condenser. This channel 22 communicates withthe nipple 26 which is piped off to the object to be lubricated, in thisinstance, the air pump.

In order to inspect the contents of the oil bowl readily, I putobservation glasses 27 in opposite sides instead of ends thereof, and ini order to get these observation glasses close together, recesses aremade in the sides of the bowl, as shown in Fig. 7. The arrange ment ofthe oil observation glassesdn the upper part of the oil bowl on itsshorter axis or transversely, instead of longitudinally, gives .a directreflection, and thus affords the operator a better and clearer view ofthe material in the bowl. The filling hole 28 likewise1 is arranged inthe upper portion of the bow As shown in Figs. 5 and 7, the bowl may bemade with a bottom nipple 29, for purposes of cleaning, and this nipplehas a screwplug closure 30. At this point also the drainage valve 31 anddrainage tube 32 may be located.

The nipple 29 is. made symmetrical with the nipple 33 in whichterminates the channel 19, and both nipples are plugged. These nipplesafford cavities or core supports for casting the bowl. The oil-bowl hasin its bottom a nipple 33, which projects a very short distancetherefrom, and much less than the nipple 16. The nipple 33 has a tubularscrew-plug 34 to receive the pipe 20,- and it is closed by the solidplug 35. By removal of the plug 35 the nipple 33 is adapted to receivethe valve 18, which in that case seats in the plug 34, and the plug 35may replace the valve in the nipple 16. This interchangeability of partsis particularly valuable in placing the lubricator in a cramped spaceand where there would be no room for the extended stern of the valve 18.

As shown in Fig. 8, the water-valve comprises a stem 36 on which ismounted the valve proper 37 having a seat 38 in part communicating withthe water-pipe-socket 39. This valve may be set at any an le desired.The condenser 4 is connected with the steam boiler by means of a union40, and this union has any number of nipples corresponding with thenumber of objects to be lubricated and connected with them by suitablepipes, as 41, Figs. 1 and 2. It sometimes occurs that the water ofcondensation overflows from the union which connects the boiler, thecondenser, and the feeds, in a pipe 42 leading to the air pump feed, andin order to overothers.

come this, a pocket 43 is formed in the union, and a dam 44 thrownacross the entrance to the said feed-pipe from said pocket, so as toexclude such condense water from the said feed-pipe. There are two pipes41, one on each side of the pocket 43, and these pipes 41' lead tonipples 45 which are connected with the engine cylinders.

As shown in Fig. 1, the oil bowl is adapted to receive at any one of itssight feed nipples a hand-feed for use in case of necessity; and

the hand-feed herein shown as applied to the lower feed comprises a cup46 having an inlet opening 47 covered by a hand-valve 48 screwing into atube 49 which rises from the bottom of the cup and which is perforatedtransversely at 50. Opposite this perforation and in alinement therewithare nipples 51 and 52 which serve respectively to receive thescrew-threaded portion of a valvestem 53 and the point 54, so that thesupply of oilto the part to which it is applied may be regulated by thishandvalve 53, 54. 55 is a drainage valve for the auxiliary handfeedshown. The hand-feed or auxiliary oilcup just above described and hereinshown, forms the subject, among other things, of my Patent No. 839,373,granted December 25, 1906. The condenser 4 may have applied to it anynumber of sight-feed devices so that the apparatus may be used forlubricating more than three parts, as shovs nin Figs. 9, 10, 11 and 12,and when it is desired to equip a lubricator already in place with thesefacilities for lubricating additional parts, the condenser of Figs. 1, 2and 3 may be removed and the condenser of Figs. 9 and 10 substituted forit. This condenser 56 differs in no essential particulars from thecondenser 4, excepting in its being adapted to receive sight feeddevices 57 at each side; and without further description it may be saidthat these sight feed devices are in all essential respects the same asthose hereinbefore described. In order to receive them, the condenser ismade with an oil supply tube 58 at each side communicating at 59 withthe oil bowl. A special form of coupling 60 shownin detail in Figs. 10,11 and 12 is employed, and this coupling comprises the portion 61 forunion with the nipple 62 of the con denser the nipple 63 for connectionwith the boiler the nipple 64 for connection with the air pump nipple26; the nipples 65 for connection with the sight feeds 57, and thenipples 66 for connection with the cylinder ni ples 45.

t is to be observed that in each of the sight feeds is a valve by whichthe admission of steam to the feed chamber may be controlled, so thatany one or more of these feeds may be cut out of service without in theleast interfering with the work of the These valves also permit theoperator to shut off steam from any feed when the glass therein isdefective or breaks, without necessarily shutting off steam from theengine. These valves may be positive acting, as shown, or of some wellknown automatic construction.

As already indicated, the interchangeable condensers admit of theconversion of a three-feed lubricator into a five-feed lubricator, and,moreover, it is possible to connect up two or more feed-chambers withany one part to be lubricated.

The feed-valves are herein shown as ar- I ranged horizontally and at theside, but it is Cir within my invention to arrange them otherwise bothin the feed-chamber parts and in the condenser; and so also the otherpressure valves may be arranged otherwise than as shown so long as theyperform the functions assigned to them.

hat I claim is 1. A sight feed lubricator, having a horizontallyarranged oil bowl provided with a feed-chamber at each of its ends, anda feedchamber at its bottom, there being an indeendent oil-supplychannel leading to each of said feed-chambers and made integral with theoil bowl, there being an independent steam-supply channel for eachfeed-chamber, and an independent steam-controlling valve for eachsteam-supply channel.

2. In a sight-ieed lubricator, an oil-bowl having a bottom feed-chamberprojecting downwardly therefrom, an adjacent nipple projecting a lessdistance from said bottom, there being an oil-duct leading from theoilbowl through said nipple into said feed-chamher, a valve-seat-plug insaid nipple, a closing plug for said nipple, and a valve for the 'feedchamber, said closing plug and valve being interchangeable.

3. In a sight feed lubricator, a horizontally arranged oil-bowl having acondenser-receiving nipple at its top substantially midway of itslength, and three nipples at its bottom, one of which contains a feedchamber with which another of the nipples is connected so that the feedcontrol may be interchangeably applied to either of these two nipples inaccordance with the available space chine to which the lubricator isapplied, the nipples at top and bottom being symmetrical y arrangedsubstantially as and for the purpose specified.

4. In a sight-feed lubricator, a horizontally arranged oil-bowl havingthe upper portion of its sides recessed at o )posite points so as tobring said sides into relatively close parallel proximity, andobservation glasses supported in said recesses opposite each other, andin a the shorter or transverse axis of the bowl, so

as to give a direct reflection and thereby af- IOILl. the operator agood and clear view of the material in the bowl.

5. In a sight-feed lubricator, a horizontally arranged oil-bowl, an oildelivery connection near its top, a "feed-chamber located at the bottomof the bowl, a delivery tube extending upwardly from said feed-chamberoutside of said oil-bowl, a transversely arranged tube passing from saidexternal tube crosswise of the oil-bowl and opening into saidoil-delivery connection, an independent cut-off valve for controllingcommunication between the transversely arranged tube and the external onthe ma- I tube without taking off the steam from the lubricator, and anoil-supply duct connecting the bowl and feed-chamber.

6. In a sight-feed lubricator, an oil-bowl having a condenser-nipple atits top and a number of sight-feeds arranged about its body, combinedwith a condenser having feed-chambers arranged at its sides and 1ntegraltherewith, and having integral o1l-sup ly ducts communicating with theoil-bowl, and sight-feed appurtenances arranged on said feed-chambers,applicable to the condenser-nipple on the oilbowl interchangeably with acondenser of another construction, to increase the number of sight-feedsas required and supply all from a single oil-bowl.

7. In a sight-feed lubricator, the combination of a condenser, anoil-bowl, an air-pump feed, and a boiler connection with the condenser,said boiler connection having an out let leading to and connected withthe airpump feed pipe, and a pocket adjacent thereto. provided with adam extending across the pocket next to the opening into said airpumpfeed pipe and above the center line of steam admission, to excludecondense water from the said feed pipe and admit steam to it.

8. A sight-feed lubricator comprising a horizontally arranged oil-bowl,three feedchambers applied to said oil-bowl, respectively at its endsand its bottom, there being integral oil-ducts separately connectingeach of said feed-chambers with the oil-bowl, and separatesteam-supplying mediums, a con denser mounted upon said oil-bowl andhaving integral feed-chambers at its sides, each also fed independentlyfrom the oil-bowl, and a union applied to the condenser and having asteam connection for the boiler.

9. In a sight feed lubricator, the combination of acondenser, anoil-bowl, an air-pump feed, and a boiler connection with the condenser,said boiler connection having a pocket extending up into it above thecenter line of steam admission and an outlet at said point communicatingwith a passage leading down from and around the outside of the boilerconnection, and a circulating pipe communicating with the bottom of saidpassage and the air pump feed pipe, whereby the water of condensation isexcluded from and steam admitted to the circulating pipe.

In testimony whereof I have hereunto set my hand this third day ofFebruary, A. D. 1905.
